Watch for aphids on new growth, spider mites on older leaves and cut worms on young transplants. Spray peach and plum trees for curculio weevils when 3/4 of the petals have fallen (repeat three times at two week intervals).

Prune:

Prune hibiscus, also spring flowering shrubs and trees, after they bloom. Prune and train vines. Shape spring-blooming shrubs with light pruning after bloom. Allow bulb foliage to yellow and die before removing.
